-5-

(a) Stock Subject to the Plan. Subject to the provisions of Section 15 of
the Plan, the maximum aggregate number of Shares that may be issued under the Plan is 3,500,000 Shares, plus (i) any Shares that, as of the Registration Date, have been reserved but not issued pursuant to any awards granted under the
SolarWinds, Inc. Stock Incentive Plan (the Existing Plan) and are not subject to any awards granted thereunder, and (ii) any Shares subject to stock options or similar awards granted under the Existing Plan that expire or
otherwise terminate without having been exercised in full and Shares issued pursuant to awards granted under the Existing Plan that are forfeited to or repurchased by the Company, up to a maximum of 11,265,818 Shares. The Shares may be authorized,
but unissued, or reacquired Common Stock.

(b) Automatic Share Reserve Increase. The number of Shares available for issuance under
the Plan will be increased on the first day of each Fiscal Year beginning with the 2009 Fiscal Year, in an amount equal to the lesser of (i) 6,000,000 Shares, (ii) four and three quarters percent (4.75%) of the number of Shares
outstanding on the last day of the immediately preceding Fiscal Year and (ii) such lesser number of Shares as may be determined by the Board.

Performance Shares, is forfeited to or repurchased by the Company due to failure to vest, the unpurchased Shares (or for Awards other than Options or Stock Appreciation Rights the forfeited or repurchased Shares) which were subject thereto will
become available for future grant or sale under the Plan (unless the Plan has terminated). With respect to Stock Appreciation Rights, only Shares actually issued (i.e., the net Shares issued) pursuant to a Stock Appreciation Right will cease to be
available under the Plan; all remaining Shares under Stock Appreciation Rights will remain available for future grant or sale under the Plan (unless the Plan has terminated). Shares that have actually been issued under the Plan under any Award will
not be returned to the Plan and will not become available for future distribution under the Plan; provided, however, that if Shares issued pursuant to Awards of Restricted Stock, Restricted Stock Units, Performance Shares or Performance Units are
repurchased by the Company or are forfeited to the Company, such Shares will become available for future grant under the Plan. Shares used to pay the exercise price of an Award or to satisfy the tax withholding obligations related to an Award will
become available for future grant or sale under the Plan. To the extent an Award under the Plan is paid out in cash rather than Shares, such cash payment will not result in reducing the number of Shares available for issuance under the Plan.
Notwithstanding the foregoing and, subject to adjustment as provided in Section 15, the maximum number of Shares that may be issued upon the exercise of Incentive Stock Options will equal the aggregate Share number stated in Section 3(a),
plus, to the extent allowable under Section 422 of the Code and the Treasury Regulations promulgated thereunder, any Shares that become available for issuance under the Plan pursuant to Sections 3(b) and 3(c).

(d) Share Reserve. The Company, during the term of this Plan, will at all times reserve and keep available such number of Shares as will be
sufficient to satisfy the requirements of the Plan.

4. Administration of the Plan.

(a) Procedure.

(i) Multiple
Administrative Bodies. Different Committees with respect to different groups of Service Providers may administer the Plan.

(ii)
Section 162(m). To the extent that the Administrator determines it to be desirable to qualify Awards granted hereunder as performance-based compensation within the meaning of Section 162(m) of the Code, the Plan will be
administered by a Committee of two (2) or more outside directors within the meaning of Section 162(m) of the Code.

(iii) Rule 16b-3. To the extent desirable to qualify transactions hereunder as exempt under Rule 16b-3, the transactions contemplated hereunder will be structured to satisfy the requirements for exemption under Rule 16b-3.

(iv) Other Administration. Other than as provided above, the Plan will be administered by (A) the Board or (B) a
Committee, which committee will be constituted to satisfy Applicable Laws.

(b) Powers of the Administrator. Subject to the
provisions of the Plan, and in the case of a Committee, subject to the specific duties delegated by the Board to such Committee, the Administrator will have the authority, in its discretion:

(i) to determine the Fair Market Value;

(ii) to select the Service Providers to whom Awards may be granted hereunder;

(iii) to determine the number of Shares to be
covered by each Award granted hereunder;

(iv) to approve forms of Award Agreements for use under the Plan;

include, but are not limited to, the exercise price, the time or times when Awards may be exercised (which may be based on performance criteria), any vesting acceleration or waiver of forfeiture restrictions, and any restriction or limitation
regarding any Award or the Shares relating thereto, based in each case on such factors as the Administrator will determine;

regulations relating to sub-plans established for the purpose of satisfying applicable foreign laws;

(ix) to modify or amend each Award
(subject to Section 20(c) of the Plan), including but not limited to the discretionary authority to extend the post-termination exercisability period of Awards and to extend the maximum term of an Option (subject to Section 6(b) regarding
Incentive Stock Options);

(x) to allow Participants to satisfy withholding tax obligations in such manner as prescribed in
Section 16;

(xi) to authorize any person to execute on behalf of the Company any instrument required to effect the grant of an Award
previously granted by the Administrator;

(xii) to allow a Participant to defer the receipt of the payment of cash or the delivery of
Shares that would otherwise be due to such Participant under an Award; and

(xiii) to make all other determinations deemed necessary or
advisable for administering the Plan.

(c) Effect of Administrators Decision. The Administrators decisions,
determinations and interpretations will be final and binding on all Participants and any other holders of Awards.

(d) No Liability.
Under no circumstances shall the Company, its Affiliates, the Administrator, or the Board incur liability for any indirect, incidental, consequential or special damages (including lost profits) of any form incurred by any person, whether or not
foreseeable and regardless of the form of the act in which such a claim may be brought, with respect to the Plan or the Companys, its Affiliates, the Administrators or the Boards roles in connection with the Plan.

5. Eligibility. Nonstatutory Stock Options, Restricted Stock, Restricted Stock Units, Performance Units, and Performance Shares may be granted
to Service Providers. Incentive Stock Options may be granted only to employees of the Company or any Parent or Subsidiary of the Company.

6. Stock Options.

(a) Limitations. Each Option will be designated in the Award Agreement as either an Incentive
Stock Option or a Nonstatutory Stock Option. However, notwithstanding such designation, to the extent that the aggregate Fair Market Value of the Shares with respect to which Incentive Stock Options are exercisable for the first time by the
Participant during any calendar year (under all plans of the Company and any Parent or Subsidiary) exceeds one hundred thousand dollars ($100,000), such Options will be treated as Nonstatutory Stock Options. For purposes of this Section 6(a),
Incentive Stock Options will be taken into account in the order in which they were granted. The Fair Market Value of the Shares will be determined as of the time the Option with respect to such Shares is granted.

-8-

(b) Term of Option. The term of each Option will be stated in the Award Agreement. In the case of
an Incentive Stock Option, the term will be ten (10) years from the date of grant or such shorter term as may be provided in the Award Agreement. Moreover, in the case of an Incentive Stock Option granted to a Participant who, at the time the
Incentive Stock Option is granted, owns stock representing more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or any Parent or Subsidiary, the term of the Incentive Stock Option will be five
(5) years from the date of grant or such shorter term as may be provided in the Award Agreement.

(c) Option Exercise Price and
Consideration.

(i) The per Share exercise price for the Shares to be issued pursuant to the exercise of an Option will be determined
by the Administrator, but will be no less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. In addition, in the case of an Incentive Stock Option granted to an employee of the Company or any Parent or
Subsidiary of the Company who owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the per Share exercise price will be no less than one hundred ten percent
(110%) of the Fair Market Value per Share on the date of grant. Notwithstanding the foregoing provisions of this Section 6(c)(i), Options may be granted with a per Share exercise price of less than one hundred percent (100%) of the
Fair Market Value per Share on the date of grant pursuant to a transaction described in, and in a manner consistent with, Code Section 424(a).

(ii) Waiting Period and Exercise Dates. At the time an Option is granted, the Administrator will fix the period within which the Option may be exercised and will determine any conditions that must be satisfied
before the Option may be exercised.

(iii) Form of Consideration. The Administrator will determine the acceptable form of
consideration for exercising an Option, including the method of payment. In the case of an Incentive Stock Option, the Administrator will determine the acceptable form of consideration at the time of grant. Such consideration may consist entirely
of: (1) cash; (2) check; (3) promissory note, to the extent permitted by Applicable Laws, (4) other Shares, provided that such Shares have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the
Shares as to which such Option will be exercised and provided further that accepting such Shares will not result in any adverse accounting consequences to the Company, as the Administrator determines in its sole discretion; (5) consideration
received by the Company under cashless exercise program (whether through a broker or otherwise) implemented by the Company in connection with the Plan; (6) by net exercise; (7) such other consideration and method of payment for the
issuance of Shares to the extent permitted by Applicable Laws; or (8) any combination of the foregoing methods of payment.

(d)
Exercise of Option.

(i) Procedure for Exercise; Rights as a Stockholder. Any Option granted hereunder will be exercisable
according to the terms of the Plan and at such times and under such conditions as determined by the Administrator and set forth in the Award Agreement. An Option may not be exercised for a fraction of a Share.

-9-

An Option will be deemed exercised when the Company receives: (i) notice of exercise (in such form
as the Administrator may specify from time to time) from the person entitled to exercise the Option, and (ii) full payment for the Shares with respect to which the Option is exercised (together with applicable withholding taxes). Full payment
may consist of any consideration and method of payment authorized by the Administrator and permitted by the Award Agreement and the Plan. Shares issued upon exercise of an Option will be issued in the name of the Participant or, if requested by the
Participant, in the name of the Participant and his or her spouse. Until the Shares are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive
dividends or any other rights as a stockholder will exist with respect to the Shares subject to an Option, notwithstanding the exercise of the Option. The Company will issue (or cause to be issued) such Shares promptly after the Option is exercised.
No adjustment will be made for a dividend or other right for which the record date is prior to the date the Shares are issued, except as provided in Section 15 of the Plan.

Exercising an Option in any manner will decrease the number of Shares thereafter available, both for purposes of the Plan and for sale under the Option,
by the number of Shares as to which the Option is exercised.

(ii) Termination of Relationship as a Service Provider. If a
Participant ceases to be a Service Provider, other than upon the Participants termination as the result of the Participants death or Disability, the Participant may exercise his or her Option within such period of time as is specified in
the Award Agreement to the extent that the Option is vested on the date of termination (but in no event later than the expiration of the term of such Option as set forth in the Award Agreement). In the absence of a specified time in the Award
Agreement, the Option will remain exercisable for three (3) months following the Participants termination. Unless otherwise provided by the Administrator, if on the date of termination the Participant is not vested as to his or her entire
Option, the Shares covered by the unvested portion of the Option will revert to the Plan. If after termination the Participant does not exercise his or her Option within the time specified by the Administrator, the Option will terminate, and the
Shares covered by such Option will revert to the Plan.

(iii) Disability of Participant. If a Participant ceases to be a Service
Provider as a result of the Participants Disability, the Participant may exercise his or her Option within such period of time as is specified in the Award Agreement to the extent the Option is vested on the date of termination (but in no
event later than the expiration of the term of such Option as set forth in the Award Agreement). In the absence of a specified time in the Award Agreement, the Option will remain exercisable for twelve (12) months following the
Participants termination. Unless otherwise provided by the Administrator, if on the date of termination the Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option will revert to the
Plan. If after termination the Participant does not exercise his or her Option within the time specified herein, the Option will terminate, and the Shares covered by such Option will revert to the Plan.

(iv) Death of Participant. If a Participant dies while a Service Provider, the Option may be exercised following the Participants death
within such period of time as is specified in the Award Agreement to the extent that the Option is vested on the date of death (but

-10-

in no event may the option be exercised later than the expiration of the term of such Option as set forth in the Award Agreement), by the Participants
designated beneficiary, provided such beneficiary has been designated prior to Participants death in a form acceptable to the Administrator. If no such beneficiary has been designated by the Participant, then such Option may be exercised by
the personal representative of the Participants estate or by the person(s) to whom the Option is transferred pursuant to the Participants will or in accordance with the laws of descent and distribution. In the absence of a specified time
in the Award Agreement, the Option will remain exercisable for twelve (12) months following Participants death. Unless otherwise provided by the Administrator, if at the time of death Participant is not vested as to his or her entire
Option, the Shares covered by the unvested portion of the Option will immediately revert to the Plan. If the Option is not so exercised within the time specified herein, the Option will terminate, and the Shares covered by such Option will revert to
the Plan.

(v) Termination for Cause. If a Participants status as a Service Provider is terminated for Cause, then the Option
will immediately terminate, and the Shares covered by such Option will revert to and again become available for issuance under the Plan.

7. Restricted Stock.

(a) Grant of Restricted Stock. Subject to the terms and provisions of the Plan, the
Administrator, at any time and from time to time, may grant Shares of Restricted Stock to Service Providers in such amounts as the Administrator, in its sole discretion, will determine.

(b) Restricted Stock Agreement. Each Award of Restricted Stock will be evidenced by an Award Agreement that will specify the Period of
Restriction, the number of Shares granted, and such other terms and conditions as the Administrator, in its sole discretion, will determine. Unless the Administrator determines otherwise, the Company as escrow agent will hold Shares of Restricted
Stock until the restrictions on such Shares have lapsed.

(c) Transferability. Except as provided in this Section 7, Shares of
Restricted Stock may not be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated until the end of the applicable Period of Restriction.

(d) Other Restrictions. The Administrator, in its sole discretion, may impose such other restrictions on Shares of Restricted Stock as it may deem advisable or appropriate.

(e) Removal of Restrictions. Except as otherwise provided in this Section 7, Shares of Restricted Stock covered by each Restricted Stock
grant made under the Plan will be released from escrow as soon as practicable after the last day of the Period of Restriction or at such other time as the Administrator may determine. The Administrator, in its discretion, may accelerate the time at
which any restrictions will lapse or be removed.

(f) Voting Rights. During the Period of Restriction, Service Providers holding
Shares of Restricted Stock granted hereunder may exercise full voting rights with respect to those Shares, unless the Administrator determines otherwise.

(g) Dividends and Other Distributions. During the Period of Restriction, Service Providers holding Shares of Restricted Stock will be entitled to receive all dividends and

-11-

other distributions paid with respect to such Shares, unless the Administrator provides otherwise. If any such dividends or distributions are paid in Shares,
the Shares will be subject to the same restrictions on transferability and forfeitability as the Shares of Restricted Stock with respect to which they were paid.

(h) Return of Restricted Stock to Company. On the date set forth in the Award Agreement, the Restricted Stock for which restrictions have not lapsed will revert to the Company and again will become available
for grant under the Plan.

8. Restricted Stock Units.

(a) Grant. Restricted Stock Units may be granted at any time and from time to time as determined by the Administrator. After the Administrator determines that it will grant Restricted Stock Units under the
Plan, it will advise the Participant in an Award Agreement of the terms, conditions, and restrictions related to the grant, including the number of Restricted Stock Units.

(b) Vesting Criteria and Other Terms. The Administrator will set vesting criteria in its discretion, which, depending on the extent to which the
criteria are met, will determine the number of Restricted Stock Units that will be paid out to the Participant. The Administrator may set vesting criteria based upon the achievement of Company-wide, business unit, or individual goals (including, but
not limited to, continued employment), or any other basis determined by the Administrator in its discretion.

(c) Earning Restricted
Stock Units. Upon meeting the applicable vesting criteria, the Participant will be entitled to receive a payout as determined by the Administrator. Notwithstanding the foregoing, at any time after the grant of Restricted Stock Units, the
Administrator, in its sole discretion, may reduce or waive any vesting criteria that must be met to receive a payout.

(d) Form and
Timing of Payment. Payment of earned Restricted Stock Units will be made as soon as practicable after the date(s) determined by the Administrator and set forth in the Award Agreement. The Administrator, in its sole discretion, may only settle
earned Restricted Stock Units in cash, Shares, or a combination of both.

pursuant to exercise of a Stock Appreciation Right will be determined by the Administrator and will be no less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. Otherwise, the Administrator, subject to the
provisions of the Plan, will have complete discretion to determine the terms and conditions of Stock Appreciation Rights granted under the Plan.

(d) Stock Appreciation Right Agreement. Each Stock Appreciation Right grant will be evidenced by an Award Agreement that will specify the exercise price, the term of the Stock Appreciation Right, the conditions of exercise, and such
other terms and conditions as the Administrator, in its sole discretion, will determine.

(e) Expiration of Stock Appreciation
Rights. A Stock Appreciation Right granted under the Plan will expire upon the date determined by the Administrator, in its sole discretion, and set forth in the Award Agreement. Notwithstanding the foregoing, the rules of Section 6(b)
relating to the maximum term and Section 6(d) relating to exercise also will apply to Stock Appreciation Rights.

(f) Payment of
Stock Appreciation Right Amount. Upon exercise of a Stock Appreciation Right, a Participant will be entitled to receive payment from the Company in an amount determined by multiplying:

(i) The difference between the Fair Market Value of a Share on the date of exercise over the exercise price; times

(ii) The number of Shares with respect to which the Stock Appreciation Right is exercised.

At the discretion of the Administrator, the payment upon Stock Appreciation Right exercise may be in cash, in Shares of equivalent value, or in some
combination thereof.

10. Performance Units and Performance Shares.

(a) Grant of Performance Units/Shares. Performance Units and Performance Shares may be granted to Service Providers at any time and from time to

date of grant. Each Performance Share will have an initial value equal to the Fair Market Value of a Share on the date of grant.

(c)
Performance Objectives and Other Terms. The Administrator will set performance objectives or other vesting provisions (including, without limitation, continued status as a Service Provider) in its discretion which, depending on the extent to
which they are met, will determine the number or value of Performance Units/Shares that will be paid out to the

-13-

Service Providers. The time period during which the performance objectives or other vesting provisions must be met will be called the Performance
Period. Each Award of Performance Units/Shares will be evidenced by an Award Agreement that will specify the Performance Period, and such other terms and conditions as the Administrator, in its sole discretion, will determine. The
Administrator may set performance objectives based upon the achievement of Company-wide, divisional, or individual goals, applicable federal or state securities laws, or any other basis determined by the Administrator in its discretion.

(d) Earning of Performance Units/Shares. After the applicable Performance Period has ended, the holder of Performance Units/Shares will be
entitled to receive a payout of the number of Performance Units/Shares earned by the Participant over the Performance Period, to be determined as a function of the extent to which the corresponding performance objectives or other vesting provisions
have been achieved. After the grant of a Performance Unit/Share, the Administrator, in its sole discretion, may reduce or waive any performance objectives or other vesting provisions for such Performance Unit/Share.

(e) Form and Timing of Payment of Performance Units/Shares. Payment of earned Performance Units/Shares will be made as soon as practicable after
the expiration of the applicable Performance Period. The Administrator, in its sole discretion, may pay earned Performance Units/Shares in the form of cash, in Shares (which have an aggregate Fair Market Value equal to the value of the earned
Performance Units/Shares at the close of the applicable Performance Period) or in a combination thereof.

(f) Cancellation of
Performance Units/Shares. On the date set forth in the Award Agreement, all unearned or unvested Performance Units/Shares will be forfeited to the Company, and again will be available for grant under the Plan.

11. Formula Awards to Outside Directors.

(a) General. Outside Directors will be entitled to receive all types of Awards (except Incentive Stock Options) under this Plan, including discretionary Awards not covered under this Section 11. All grants of Awards to Outside
Directors pursuant to this Section will be automatic and nondiscretionary, except as otherwise provided herein, and will be made in accordance with the following provisions:

(b) Type of Option. If Options are granted pursuant to this Section they will be Nonstatutory Stock Options and, except as otherwise provided
herein, will be subject to the other terms and conditions of the Plan.

(c) No Discretion. No person will have any discretion to
select which Outside Directors will be granted Awards under this Section or to determine the number of Shares to be covered by such Awards (except as provided in Sections 11 and 14).

(d) Initial Award. Each person who first becomes an Outside Director following the Registration Date will be automatically granted an Option to
purchase 30,000 Shares (the Initial Award) on or about the date on which such person first becomes an Outside Director, whether through election by the stockholders of the Company or appointment by the

-14-

Board to fill a vacancy; provided, however, that an Inside Director who ceases to be an Inside Director, but who remains a Director, will not receive an
Initial Award.

(e) Annual Award. Each Outside Director will be automatically granted (an Annual Award) on each date of
the annual meeting of the stockholders of the Company beginning in 2008, if as of such date, he or she will have served on the Board for at least the preceding six (6) months (i) an Option to purchase a number of Shares determined by
dividing (A) $75,000, by (B) the value of an Option to purchase one Share with the same terms set forth below for an Option granted pursuant to the Annual Award determined using the Black-Scholes valuation model or such other valuation
method as the Administrator determines in its discretion, with the number of Shares rounded up to the nearest whole Share, and (ii) a number of Shares of Restricted Stock determined by dividing (A) $25,000 by (B) the Fair Market Value
of a Share on the date of grant, with the number of Shares rounded up to the nearest whole Share.

(f) Terms. The terms of each
Award granted pursuant to this Section will be as follows:

(i) The term of an Option granted under this Section 11 will be
ten (10) years.

(ii) The exercise price for Shares subject to Options granted under this Section 11 will be one
hundred percent (100%) of the Fair Market Value on the grant date.

(iii) Subject to Section 15, the Initial Award will vest and
become exercisable over a three (3) year period with one-third (1/3) of the Shares subject to the Initial Award vesting on the first anniversary of the vesting commencement date, and 1/36 of the Shares subject to the Initial Award vesting
on the last day of each full calendar month thereafter, provided that the Participant continues to serve as a Director through such dates.

(iv) Subject to Section 15, the Options granted under an Annual Award will vest and become exercisable as to one hundred percent (100%) of the Shares subject to such Option on the earlier of (i) the date of the next
annual meeting following the date of grant or (ii) the December 31 of the calendar year following the calendar year in which the grant occurs, provided that the Participant continues to serve as a Director through such date.

(v) The Restricted Stock awarded under the Annual Award will be issued for no cash consideration and will be forfeited and automatically transferred to
and reacquired by the Company at no cost to the Company upon the date the Director ceases to provide services as a member of the Board (the Forfeiture Provision). The Forfeiture Provision will lapse on the earlier of
(i) the date of the next annual meeting following the date of grant of the award or (ii) the December 31 of the calendar year following the calendar year in which the award is granted, provided that the Participant continues
to serve as a Director through such date.

(g) Adjustments. The Administrator in its discretion may change and otherwise revise the
terms of Awards granted under this Section 11, including, without limitation, the number of Shares and exercise prices thereof, for Awards granted on or after the date the Administrator determines to make any such change or revision.

-15-

12. Compliance With Code Section 409A. Awards will be designed and operated in such a manner
that they are either exempt from the application of, or comply with, the requirements of Code Section 409A such that the grant, payment, settlement or deferral will not be subject to the additional tax or interest applicable under Code
Section 409A, except as otherwise determined in the sole discretion of the Administrator. The Plan and each Award Agreement under the Plan is intended to meet the requirements of Code Section 409A and will be construed and interpreted
in accordance with such intent, except as otherwise determined in the sole discretion of the Administrator. To the extent that an Award or payment, or the settlement or deferral thereof, is subject to Code Section 409A the Award will be
granted, paid, settled or deferred in a manner that will meet the requirements of Code Section 409A, such that the grant, payment, settlement or deferral will not be subject to the additional tax or interest applicable under Code
Section 409A.

13. Leaves of Absence/Transfer Between Locations. Unless
the Administrator provides otherwise, vesting of Awards granted hereunder will be suspended during any unpaid leave of absence. A Participant will not cease to be an Employee in the case of (i) any leave of absence approved by the Company or
(ii) transfers between locations of the Company or between the Company, its Parent, or any Subsidiary. For purposes of Incentive Stock Options, no such leave may exceed three (3) months, unless reemployment upon expiration of such leave is
guaranteed by statute or contract. If reemployment upon expiration of a leave of absence approved by the Company is not so guaranteed, then six (6) months following the first (1st) day of such leave, any Incentive Stock Option held by the Participant will cease to be treated as an Incentive Stock Option and will be treated for tax purposes as a
Nonstatutory Stock Option.

14. Transferability of Awards. Unless determined otherwise by the Administrator, an Award may not be
sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent or distribution and may be exercised, during the lifetime of the Participant, only by the Participant. If the Administrator
makes an Award transferable, including, without limitation, by instrument to an inter vivos or testamentary trust in which the Awards are to be passed to beneficiaries upon the death of the trustor (settlor) or by gift to Family Members, such Award
will contain such additional terms and conditions as the Administrator deems appropriate.

15. Adjustments; Dissolution or Liquidation;
Merger or Change in Control.

(a) Adjustments. In the event that any dividend or other distribution (whether in the form of
cash, Shares, other securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Shares or other securities of the Company, or
other change in the corporate structure of the Company affecting the Shares occurs, the Administrator, in order to prevent diminution or enlargement of the benefits or potential benefits intended to be made available under the Plan, will adjust the
number and class of Shares that may be delivered under the Plan and/or the number, class, and price of Shares covered by each outstanding Award, the numerical Share limits in Section 3 of the Plan, and the number of Shares issuable pursuant to
Awards to be granted under Section 11 of the Plan.

-16-

(b) Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the
Company, the Administrator will notify each Participant as soon as practicable prior to the effective date of such proposed transaction. To the extent it has not been previously exercised, an Award will terminate immediately prior to the
consummation of such proposed action.

(c) Change in Control. In the event of a merger or Change in Control, each outstanding Award
will be treated as the Administrator determines without a Participants consent, including, without limitation, that (i) Awards will be assumed, or substantially equivalent Awards will be substituted, by the acquiring or succeeding
corporation (or an affiliate thereof) with appropriate adjustments as to the number and kind of shares and prices; (ii) upon written notice to a Participant, that the Participants Awards will terminate immediately prior to the
consummation of such merger or Change in Control; (iii) outstanding Awards will vest and become exercisable, realizable, or payable, or restrictions applicable to an Award will lapse, in whole or in part prior to or upon consummation of such
merger or Change in Control, and, to the extent the Administrator determines, terminate upon the effectiveness of such merger of Change in Control; (iv) (A) the termination of an Award in exchange for an amount of cash and/or property, if
any, equal to the amount that would have been attained upon the exercise of such Award or realization of the Participants rights as of the date of the occurrence of the transaction (and, for the avoidance of doubt, if as of the date of the
occurrence of the transaction the Administrator determines in good faith that no amount would have been attained upon the exercise of such Award or realization of the Participants rights, then such Award may be terminated by the Company
without payment), or (B) the replacement of such Award with other rights or property selected by the Administrator in its sole discretion; or (v) any combination of the foregoing. In taking any of the actions permitted under this
subsection 15(c), the Administrator will not be obligated to treat all Awards, all Awards held by a Participant, or all Awards of the same type, similarly.

In the event that the successor corporation does not assume or substitute for the Award, the Participant will fully vest in and have the right to exercise all of his or her outstanding Options and Stock Appreciation
Rights, including Shares as to which such Awards would not otherwise be vested or exercisable, all restrictions on Restricted Stock and Restricted Stock Units will lapse, and, with respect to Awards with performance-based vesting, all performance
goals or other vesting criteria will be deemed achieved at one hundred percent (100%) of target levels and all other terms and conditions met. In addition, if an Option or Stock Appreciation Right is not assumed or substituted in the event of a
Change in Control, the Administrator will notify the Participant in writing or electronically that the Option or Stock Appreciation Right will be exercisable for a period of time determined by the Administrator in its sole discretion, and the Option
or Stock Appreciation Right will terminate upon the expiration of such period.

For the purposes of this subsection (c), an Award will be
considered assumed if, following the Change in Control, the Award confers the right to purchase or receive, for each Share subject to the Award immediately prior to the Change in Control, the consideration (whether stock, cash, or other securities
or property) received in the Change in Control by holders of Common Stock for each Share held on the effective date of the transaction (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of

-17-

a majority of the outstanding Shares); provided, however, that if such consideration received in the Change in Control is not solely common stock of the
successor corporation or its Parent, the Administrator may, with the consent of the successor corporation, provide for the consideration to be received upon the exercise of an Option or Stock Appreciation Right or upon the payout of a Restricted
Stock Unit, Performance Unit or Performance Share, for each Share subject to such Award, to be solely common stock of the successor corporation or its Parent equal in fair market value to the per share consideration received by holders of Common
Stock in the Change in Control.

Notwithstanding anything in this Section 15(c) to the contrary, an Award that vests, is earned or
paid-out upon the satisfaction of one or more performance goals will not be considered assumed if the Company or its successor modifies any of such performance goals without the Participants consent; provided, however, a modification to such
performance goals only to reflect the successor corporations post-Change in Control corporate structure will not be deemed to invalidate an otherwise valid Award assumption.

(d) Outside Director Awards. With respect to Awards granted to an Outside Director that are assumed or substituted for, if on the date of or
following such assumption or substitution the Participants status as a Director or a director of the successor corporation, as applicable, is terminated other than upon a voluntary resignation by the Participant (unless such resignation is at
the request of the acquirer), then the Participant will fully vest in and have the right to exercise Options and/or Stock Appreciation Rights as to all of the Shares underlying such Award, including those Shares which would not otherwise be vested
or exercisable, all restrictions on Restricted Stock and Restricted Stock Units will lapse, and, with respect to Performance Units and Performance Shares, all performance goals or other vesting criteria will be deemed achieved at one hundred percent
(100%) of target levels and all other terms and conditions met.

16. Tax Withholding.

(a) Withholding Requirements. Prior to the delivery of any Shares or cash pursuant to an Award (or exercise thereof), the Company will have the
power and the right to deduct or withhold, or require a Participant to remit to the Company, an amount sufficient to satisfy federal, state, local, foreign or other taxes (including the Participants FICA obligation) required to be withheld
with respect to such Award (or exercise thereof).

(b) Withholding Arrangements. The Administrator, in its sole discretion and
pursuant to such procedures as it may specify from time to time, may permit a Participant to satisfy such tax withholding obligation, in whole or in part by (without limitation) (a) paying cash, (b) electing to have the Company withhold
otherwise deliverable cash or Shares having a Fair Market Value equal to the minimum statutory amount required to be withheld, or (c) delivering to the Company already-owned Shares having a Fair Market Value equal to the minimum statutory
amount required to be withheld. The Fair Market Value of the Shares to be withheld or delivered will be determined as of the date that the taxes are required to be withheld.

17. No Effect on Employment or Service. Neither the Plan nor any Award will confer upon a Participant any right with respect to continuing the
Participants relationship as a

-18-

Service Provider with the Company, nor will they interfere in any way with the Participants right or the Companys right to terminate such
relationship at any time, with or without cause, to the extent permitted by Applicable Laws.

18. Date of Grant. The date of grant
of an Award will be, for all purposes, the date on which the Administrator makes the determination granting such Award, or such other later date as is determined by the Administrator. Notice of the determination will be provided to each Participant
within a reasonable time after the date of such grant.

19. Term of Plan. Subject to Section 23 of the Plan, the Plan will
become effective upon its adoption by the Board. It will continue in effect for a term of ten (10) years from the date adopted by the Board, unless terminated earlier under Section 20 of the Plan.

20. Amendment and Termination of the Plan.

(a) Amendment and Termination. The Board may at any time amend, alter, suspend or terminate the Plan.

(b) Stockholder
Approval. The Company will obtain stockholder approval of any Plan amendment to the extent necessary and desirable to comply with Applicable Laws.

(c) Effect of Amendment or Termination. No amendment, alteration, suspension or termination of the Plan will impair the rights of any Participant, unless mutually agreed otherwise between the Participant and
the Administrator, which agreement must be in writing and signed by the Participant and the Company. Termination of the Plan will not affect the Administrators ability to exercise the powers granted to it hereunder with respect to Awards
granted under the Plan prior to the date of such termination.

21. Conditions Upon Issuance of Shares.

(a) Legal Compliance. Shares will not be issued pursuant to the exercise of an Award unless the exercise of such Award and the issuance and
delivery of such Shares will comply with Applicable Laws and will be further subject to the approval of counsel for the Company with respect to such compliance.

(b) Investment Representations. As a condition to the exercise of an Award, the Company may require the person exercising such Award to represent and warrant at the time of any such exercise that the Shares are
being purchased only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation is required.

22. Inability to Obtain Authority. The inability of the Company to obtain authority from any regulatory body having jurisdiction, which authority
is deemed by the Companys counsel to be necessary to the lawful issuance and sale of any Shares hereunder, will relieve the Company of any liability in respect of the failure to issue or sell such Shares as to which such requisite authority
will not have been obtained.

-19-

23. Stockholder Approval. The Plan will be subject to approval by the stockholders of the Company
within twelve (12) months after the date the Plan is adopted by the Board. Such stockholder approval will be obtained in the manner and to the degree required under Applicable Laws.
